Standard Pistons or bigger

Hey guys I'm looking for some input, I'm getting ready to start building my 12 valve. It's going to be a dedicated puller. What I am wondering is to stay with standard size piston bore or bore it out bigger, will there be a big enough gain with .20 or .40 over pistons or should I save my money and spend it on something else?

Leave it std bore

Only bore it out if a cylinder is messed up. Otherwise just leave it stock.

Ok thanks guys. Is it for reliability reasons?

 

[DISTURBED]

Not really reliability but if you have an issue down the road then you have that many more times it can be fixed. Plus there really isn't must gain

Also should I go with the large bowl or stay with the stock bowl?

Stock bowls would not be the best choice.

286110 or 286210 would be a lot better of a choice for Pistons. Contact ^^^^^^^ the guy above
